The Client

LEW Lechwerke is an energy service provider located in Augsburg, Bavaria.

LEW Lechwerke wanted to provide a digital customer account for its customers. A cooperative team of developers from LEW Lechwerke and byte5 were in charge of the technical implementation. The Kundenkonto Online (Customer Account Online), a browser application for the self-administration of customers, was realised within a short time. The technical implementation was made possible by the open source CMS Umbraco and the JavaScript framework AngularJS, which created a strong unity. A third system was added for the preservation of existing data.

The Highlights

  • conception and technical implementation of the customer dashboard
  • high-performance browser application based on Umbraco and AngularJS
  • SAP gateway for the delivery of data
  • a cooperative team enabled this high-quality technical solution
  • successful project completion within a short time

The Challenges

The existing customer dashboard was very outdated and was to become more modern and user-friendly by the use of new technology. Right from the start, it was clear to LEW Lechwerke that the team would need support to realise the Customer Account Online (KKO) project in the best way possible. As a satisfied long-term client, they entrusted their newest Umbraco project to the byte5 experts, because of their high qualifications.

A dashboard, Kundenkonto Online, was to be designed and developed with which customers could edit and manage their personal data in the browser. LEW Lechwerke required that the system be multi-contract capable and that information such as master data, meter data, and invoices could be viewed and edited. While the driving force in the backend would be Umbraco as a content management system, AngularJS would be used in the frontend. The SAP gateway, with which data would be requested and distributed in the KKO interface, was particularly challenging to implement.

The Solution

For byte5, the implementation of the user dashboard began with the application’s conception. All project processes were completely agile. In a cooperative team consisting of developers from both LEW Lechwerke and byte5, the KKO user dashboard was realised within a few months. The open data protocol interface ensures the connection to SAP. This enables the transfer of data that is delivered to the dashboard. The Kundenkonto Online does not only shine with its range of functions, but above all with its performance – made possible by the smooth interaction of Umbraco in the backend and the AngularJS stack in the front end. Umbraco’s versatility was particularly valuable in development. AngularJS integrated itself seamlessly into the frontend.

The developers of byte5 are very experienced and qualified. As usual, the cooperation in this project was fantastic.

The Result

KKO offers LEW Lechwerke’s customers a significantly greater convenience than its predecessor. They can manage their data with easily with KKO. The browser application is very clearly structured and intuitive to use, even for inexperienced users. KKO handles asynchronous SAP requests easily thanks to the SignalR programme library. After this successful implementation, byte5 continues to support LEW Lechwerke with maintenance of the Kundenkonto Online. Other cooperative projects between LEW Lechwerke and byte5 are ongoing.

With KKO, byte5 has developed a solution that offers our customers a good overview. You can find all important data at a glance – it’s exactly what we wanted.
